1 Claim. (01.160-403) My invention relates to new and useful improvements in window units especially adapted for installation in trailers.

One of the objects of the present invention is to provide a unit which includes a screen, a frame, and a sash, so that the unit as a whole may be quickly and readily installed in trailers and with but little carpentry work.

Still another object of the invention is to provide a unit that is relatively light in weight, the only metal being the screen mesh and several bolts and hinges.

Still another object of the invention is to provide a window unit that is so constructed that the necessity of Weatherstripping is dispensed with. i

Still another object of the invention is to prvide an extremely light window unit especially adapted for trailers whereinthe frame and sash are double rabbeted so that there is a tight fit between the sash and the frame when the sash is closed to thus prevent any water from leaking around the sash and into the frame and trailer.

Still another object of the invention is to provide a unit wherein the main body of the frame may be built to accommodate the forward face portion of the frame whose depth will be regulated by the cross-sectional dimension or thickness of the sash that is to be installed in the frame.

Still another object of the invention is to provide a. unit which consists of the screen and its frame which will be fastened to the rear face of the main body of the frame, while secured to the other face of the body of the frame is the front or face portion of the frame. Also, the main body of the frame and the front face of the frame are so arranged that in the assembly of the unit the depth of the front face and body of the frame may be made to accommodate a sash of a desired thickness.

Still another object of the invention is to provide a unit comprising a screen, frame and sash that will be, when installed, Waterproof, light in weight, and the sash easy to operate from within the trailer.

With these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts as will be hereinafter more fully described and pointed out in the claim.

Referring now to the drawings showing a preferred embodiment,

i Fig. 1 is a front face View of the unit;

Fig. 2" is a rear view thereof Fig. 3 is a bottom plan; Fig. 4 is a longitudinal section on an enlarged scale taken on line 4-4 of Fig. 1;

Fig; 5- is a vertical section on an enlarged scale taken on. line 5':+'5" of Fig. 2;

Fig. 6 is a similar vertical section on an enlarged scale taken on line 6-45 of Fig. 2, the dotted lines showing the sash partly opened; and Fig.-v 7 is a fragmentary perspective of the unit.

It might be mentioned at the outset that the units about to'b'e described are especially adapted to be installed in automobile trailers wherein it is desirable to have fixed screens, windows or sash that may be readily opened and closed from the inside of the trailer, and the combined unit relatively ugnt inwei'glrt and waterproof. Itis alsodesirable, due to the scarcity of metal'sg to provide a unit that calls for but as little meat as possible and" at the same time be strong and serviceable use.

Referringnow to the several views and for the moment to Fig. 1, there may be seen the front face portion tof the unit, the sash 2 in which 7 I have showntwo glass panes 3 and. 4 together witha molding"- protective strip 5 or waterdri'p, which also covers the hinges 6.

Front face portion Referring now more particularly to this front face portion I of the unit, it will be seen that it consists of the frame made up of the side piece ilwith the rearwardly extending strip 9 on its rear face, and likewise there is a similar side piece I0 with its rearwardly extending strip ll. (See Fig. 4.)

The top 14 and bottom 13, as well as the side pieces 8' and I0 justym'eritioned, extend outwardly beyond the main frame which will be later mentioned, so that these extended portions may be fitted about the walls defining the openings in the trailer body which openings receive the units.

Both the top and bottom rails, as well as the sidepieces, are groovedontheir inner faces as at ll so that strips of caulking may be inserted therein before theunit isplacedwithi'n its opening'to thus prevent water from leaking in around the frame.

Mam frame The main frame likewise consists of two side pieces 18 andi9; which pieces are fitted between the bottom strip 20 and top piece 2-I, and it Will be noticed that these top" and bottom rails are provided with tongues 22 which fit in receptive grooves 23 in the respective heretofore mentioned strips l5 and I6 of the bottom and top pieces l3 and I4.

The bottom and top pieces and 2| are rabbeted as at 24, as may be seen in Fig. 5.

It will also be seen that these bottom pieces l3 and top pieces I4 with their respective strips 15 and I6 set respectively below and above the rabbeted portion 24 so that when the sash is in its closed position, there is a double rabbet between the sash and the frame.

It will also be seen that the inner face 25 of the bottom piece 13 and its strip [5 is slightly tapered to provide for drainage of water.

By using the above constructionthat is, having a front portion of the frame fitted onto the main body of the frame and the front portion having integral strips formed on the rear thereof, it will be readily understood that the depth of these strips can be designed or cut to accommodate the depth of the particular sash 2 that is to be used in the unit.

Thus if desired the main frame may be made up and carried in stock and the top and side pieces of the front portion of the frame may also be carried in stock. Then, the strips on the inner faces of the front portions may be cut down and grooved when the units are made up to thus accommodate sashes of different thicknesses.

It will be understood that when the front frame portion is secured to the main body of the frame, the parts may all be glued as well as fastened with nails or screws.

Screen frame Referring now for the moment to Fig. 12 and Fig. 4 there may be seen what I term the screen frame 26 which fits over the metal screening 21 that is to be nailed to the rear face of the main frame. This screening is preferably in one piece and cut out opposite the vertical piece or mullion 28 in the main frame. This screen frame is also nailed to the rear face of the body of the frame to become substantially an integral part of the unit and its top, bottom and sides extend out slightly beyond and overlap the respective pieces of the main frame, as may be seen at 29 in Figs. 4 and 5.

This is important as these portions 29 of the lipped edge'may be readily planed down so that the space between these lipped edges .and the rear face of the supplemental frame may accommodate trailer walls of different thicknesses.

Thus it will be seen that there is a main frame which on its rear face has secured thereto the screen frame, while to the front face of the main frame is secured the front frame portion which, as heretofore mentioned, can also be made of different depths to accommodate sashes of different thicknesses.

Sash

Referring now to the sash 2, it consists of the stiles 38 and 3| and the bottom rail 32 and top rail 33 in which are mounted the glass panes 3 and 4 and the mullion 34 being opposite the vertical piece or mullion 28 of the main frame.

The bottom rail and stiles are grooved as at 35 so that the water will run from these grooves down to the bottom rail of the frame and then run off on the outside of the frame. The bot tom rail of the sash is rabbeted as at 36 and its contacting edge is tapered to fit the tapered face 25 formed in the bottom rail l3, as may be seen from Figs. 5 and 6. l

Thus it will be seen that the frame and sash are double rabbeted to guard against any leakage of water through the frame.

Operating arm For operating the sash the mullion 34 is slotted as at 3'! and the bolt 38 passed through one end of an L-shaped operating arm 39, the arm also passing through a slot 40 in the vertical piece 28 and through an opening in the screen. The arm is preferably made of laminated wood and is provided with the notches 4| on its inner face to engage a bolt or stud 42 mounted in the slot in the vertical piece 28.

Thus, if the sash is open and the operating arm engages the pin 42 to hold the sash open, it is only necessary to move the outer end of the operating arm slightly upwardly so that the notch will be disengaged from the bolt after which the arm will be pulled inwardly and downwardly, and when the sash is entirely closed the pivoted catch 43 secured on the rear of the cross piece 23 will be turned over the tongue 44 of the handle 39 to thus hold the handle and sash in their closed position.

As may be seen in Fig. 2 there is a small block of wood 45 that slides in the track 46 and in line with the handle, so that when the sash is opened the small block wood 45 will drop towards the handle to prevent any bugs from entering between the end of the slot and the rear face of the handle.

It will be understood that screw holes 41 may be disposed at several places around the main frame so that screws may be passed therethrough to hold the unit in position in its receptive openings in the trailer.

From the foregoing it will be seen that I have provided a unit especially adapted for automobile trailers which unit consists of the sash, main frame, front face frame, and screen frame, all the parts being so constructed that they may be easily fitted and assembled.

Also the sash and frame are so constructed that no water can pass from about the sash through the frame into the trailer when the sash is closed; and finally, the sash is easily operated from within the trailer.

The entire unit is relatively light in Weight and with the exception of the hinges and to bolts and a few nails and screws, there is no metal in the entire construction.

It will be understood that many slight changes might be made in this sash and frame without departing in any way from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A wooden sash unit adapted to be bodily installed in trailers and the like, including a rabbeted main wooden frame having tongues on its front face, a supplemental wooden frame structurally integral with the main frame and having wooden strips of the desired depth extending from the rear face, the strips having grooves interfitting with the aforementioned tongues on the front face of the frame, the outer edges of said supplemental frame extending beyond the outer marginal edges of the main frame and the inner faces of the encompassing walls of the supplemental frame being positioned slightly nwardly with relation to the rabbet construction on the front face of the main frame to thereby form a double rabbeted construction withrelatien to the main frame, a screen and wooden frame therefor secured to the rear face of the main frame and the said frame also provided with portions extending beyond the marginal edges of the main frame and the space between the outwardly extending edges of the supplemental frame and the screen frame adapted to tightly encase the walls in which the unit is to be fitted, a double rabbeted pivotal wooden sash secured to the supplemental frame and of a thickness great enough to extend rearwardly through the supplemental frame and interfit with the double rabbeted frame construction to thereby prevent leakage, and means connected with the sash and extending through the main frame and the screen for operating the sash from the interior of the trailer.
